Hey, can you please solve this :) It will be dearly appreciated thank you!!

Globex Corp. has a capital structure that consists of 40% debt and 60% equity. The firm's current beta is 1.15, but management wants to understand Globex Corp.'s market risk without the effect of leverage. If Globex Corp. has a 35% tax rate, what is its unlevered beta? 0.68 O 0.96 O 0.80 O 0.84 Now consider the case of another company: U.S. Robotics Inc. has a current capital structure of 30% debt and 70% equity. Its current before-tax cost of debt is 8%, and its tax rate is 35%. It currently has a levered beta of 1.15. The risk-free rate is 3.5%, and the risk premium on the market is 7.5%. U.S. Robotics Inc. is considering changing its capital structure to 60% debt and 40% equity. Increasing the firm's level of debt will cause its before-tax cost of debt to increase to 10% First, solve for U.S. Robotics Inc.'s unlevered beta Relever U.S. Robotics Inc.'s beta using the firm's new capital structure.
